Containment Priest is excellent here, exiling anything put into play by Sneak Attack or Show and Tell instead of letting Griselbrand, Emrakul, the Aeons Torn, or Atraxa, Grand Unifier resolve as a legal permanent. Pyroblast answers their blue cards like Force of Will, Brainstorm, and Ponder, giving us a way to protect our own spells or blow out a counterspell at a key moment. Cabal Therapy is weak against a deck that wins primarily by resolving one giant payoff rather than holding a hand of interactive spells, so a single discard rarely stops them in time. Goblin Bombardment's sacrifice outlet is a lower priority than maximizing disruption and speed in this race against their one-card combo kill.
